Effects of soil temperature on a coupled photosynthesis-stomatal conductance model for four boreal tree species
In order to examine the effects of soil temperature on a coupled photosynthesis-stomatal conductance model, seedlings of trembling aspen (Populus tremuloides Michx), jack pine (Pinsu banksiana Lamb. ), black spruce (Picea ...
Ecophysiological responses of four boreal tree species to soil nitrogen supply
The ecophysiological responses of four boreal tree species, trembling aspen (Populus tremuloides Michx.), black spruce (Picea mariana (Mill.) B.S.P.), white spruce (Picea glauca (Moench) Voss), and jack pine (Pinus ...
Influence of soil temperature on ecophysiological traits of four boreal tree species
A new soil temperature control system was developed for greenhouse experiments. The system controlled soil temperature by circulating temperature-controlled water around seedling containers. The system was tested for 5, ...
Seasonal changes in gas exchange and foliar nitrogen of three conifer species growing on an Ontario boreal mixedwood site
Jack pine, black spruce and white spruce are three vital species of the Ontario boreal mixedwood forest. The purpose of this study is to compare and contrast the ecophysiological characteristics of each species and to ...
Effects of elevated carbon dioxide concentration and light on biomass morphology and physiology of black spruce and white spruce seedlings
Carbon dioxide concentration and light interactions influence competition among boreal tree species, though little is known about the exact effects. The interactive effects of [CO 2 ] and light on growth, biomass production, ...
